Serial Nos. 608281 filed December 21, 1922,

and 687,305 filed January 19, 1924;.

lhi machines of the type described in the above mentioned applications, each item of a transaction, or sale, is entered separately in the machine and then a total of all the items for each transaction is printed. WVhen the items are entered the total control lever is in its add position and before the total of the trai'isaction is printed the total lever is ad justed to its first position below its add position. This movement is eii'ected manually before the machine is operated. After the total is printed and before another transaction, or sale, can be entered, it is necessary, in the machine disclosed in the above mentioned applications, to manually return the lever to its add position. By means of the present inv-ntion the total control lever is automatically returned to the add position t the end of every itemized transaction by the machine, thus eliminating the necessity of manually returning the total lever.

In machines of this type, three lines of totalizers are usually provided and when it is desired to take either a total or sub-total from a totalizer it is necessary to move the total lever to one of a plurality of positions for selecting one of the lines of totalizers. Vfhen the total lever is moved to any one of its plurality of positions, other than the one for taking the total of an itemized transaction, the ievcr will not be automatically returned to its add position.

The method of controlling the machine by means of the total lever for total-taking operations and the various other functions of the total lever is not shown or described herein. For a detailed disclosure of these controls and functions reference may be had to the above mentioned patent.

Detailed description The machine is provided with a total control lever (F1g. 1) which is pivoted on a sleeve 31 mounted on a stud 32 in a well 'plete rotation.

' l and l), when the total lever is moved to its known manner, as shown and described in the above mentioned patent. This lever 30 is provided for controlling the machine for item entering and for total-taking operations. The full lines indicate the position of the lever when in its add position. The dot and dash lines indicate the position of the lever when it ismoved to its first position be low the add position for total-taking opn erations, which position is the one to which it is adjusted when printing a total of an itemized transaction.

The machine is provided with a main cam shaft 33 which receives one rotation in the direction of the arrow (Fig. 1) during each item entering operation and two rotations during every total-takin operation.

The cam shaft 33 may be rotated either by means of a motor, as described in the above mentioned patent, or by means of a crank (not shown) which is adapted to be clutched to a pinion 34: (Fig. 7) mounted to rotate on a hollow stud 35. The pinion 3 L meshes with a gear 36 mounted on a stud 37. The gear meshes with a gear 38 secured to the main cam shaft 33. Two rotations of the pinion 34: will give the gear 38 and shaft 33 one com- During totaltaking operations the gear 38 is given two complete rotations. The reason for giving the shaft two complete rotations during total-taking operations is well known in the art and is described in the above mentioned patent. Since this forms no part of the present invention, no further description thereof is thought necessary.

The total lever 30 is provided with a rearwardly projecting lug adapted to be moved into the path of one of two rollers first position below its add position. Th rollers 46 are mounted within an annula groove ie of a collar 45. The collar L7 is rotated during total-taking operations to causing one of the rollers 46 to engage the lug 45 for restoring the total lever to its add position.

The collar is rotated by mechanism actuated by an arm 18 1, 5 and 6), having a roller 49 held in contact with a cam 50 on the main cam shaft by a spring Mounted on the rear end of the arm 48 is a stud 51 which adapted to be engaged by a downwardly extending hook 52, pivoted on an arm 53 secured to short shaft 54. Also secured to the shaft 1 segment 55 w rich meshes with a partial gear loosely mounted on a shaft 57, upon which the collar 47 is also mounted. (See also Fig. 4).

During the latter part of the first cycle of a total-taking operation the hook 5-2 rocked to the left (Fig. 1) into the path of the stud 51. A. guide'58 is secured to the arm 48 and also supports the stud 51. The guide 58 and the rear end of the arm l8 act as a means for guiding the hook 52 into proper position to be engaged by the stud When the arm 48 is lowered by the cam 50 during the latter part of the operation of the machine, the hook 52 is lowered and by its contact with the hook 52 the segment 55 is rocked and it in turn rotates the partial gear 56' in a clockwise direction from the position shown in Fig. 1 to that shown in Fig. 6. During this clockwise movement of the partial gear 56, the collar 47 is held against rotation by a latch 59 (see also Fig. 3) which engages a notch 60 in one of the flanges of the member 47. The gear 56 is permitted to rotate independently of the collar 4i? due to a clutch connection (Fig. 4:) which is provided with a cam edge 61 on each of the clutch prongs. As the gear 56 rotates, the cam edges 61 will cause the gear 56 to be shifted toward the left (Fig. 4) against the tension of a spring 62 until said gear is disconnected from the collar 47. The right hand end of the spring 62 rests in a groove (Fig. 3) in the gear 56, and the left hand end of the spring bears against a washer 64 (see also Fig. 8).

The downward movement of the hook will drive the gear 56 through one-half rotation in a clockv. se oirection. At the end of this one-half rotation, the spring 62 will cause the gear 56 to be shifted toward the right (Fig. l) to reengage the clutch prongs with the clutch slots of the collar e7.

The downward movement of the hook 52 will also stretch a strong spring attached *0 the upper end of the arm 53. The spring 75 normally holds the arm 53 a ainst a stud T1 D s 6 (r 1g. 5) carried by the side frame 77 of the machine. Just as the machine comes to rest and the total lever is free to be moved back to its add position, in a manner to be hereinafter described, the spring 75 rotates the segment 55 in a clockwise direction, thereby rotating the gear 56 and collar 47 in a counter-clockwise direction. During the counterclockwise movement of the collar the roller 46 engages the lug l5 and restores the total lever 30 to its add position.

Before the collar 47 can be rotated in a clockwise direction, as just described, it is necessary to disengage the latch 59 from the notch 60. Mounted on the se ment 55 is a stud 80 (Fig. 3), which near tne end of the counter-clockwise movement of the segment 55, engages the arm 81 of the latch 59 thereby rotating the latch on its pivot 82 against the tension of a spring 83.

The arm 8l of the latch 59 is provided with a surface 8% long enough to maintain the latch out of the notch 60 until the periphery of the collar 47 passes beneath the nose of the latch 59. Just as the collar 47 completes its one-half rotation, the latch 59 Will be engaged with the diametrically opposite notch 60 in the flange of the collar 47, thereby preventing further rotation thereof.

Overthrow of the collar 47 is prevented by a shoulder 85 on the latch 59, which is engaged by the right hand edge of the notch 60.

During the first cycle of a total-taking operation, the hook 52 is held in a position in which it is prevented.- from engaging the stud 51 by means of a link 90 slidably mounted on studs 91 and 92. The stud 91 is mounted on a side frame of the machine, and the stud 92 is carried by an arm 93 pivoted on a stud 94. The right hand end (Fig. 1) of the, link 90 is provided with a notch 89 embracing a stud 95 on the hook 52. When the total control lever 30 is moved into any of its totaltaking positions, the hook 52 is given a slight movement toward the left, but this movement is not enough to engage it with the stud 51. This initial movement is given the hook '52 upon the manual movement of the total lever, by means of a cam slot 96 (Fig. 2) into which a stud on an arm 97 projects. The arm 97 is pivoted on a stud 98 carried by the side frame of the machine and is adapted to rock an arm 99 by means of a flexible connection in the form of a spring 100. The arm 99 is provided with a cam slot 101 which is engaged by a stud on an arm 102 secured to a shaft 103. Also secured to the shaft 103 (Fig. 1) is an arm 104, connected to the arm 93 by means of a link 105. The lower end of the arm 93 has pivoted thereto one end of a pitman 106 (see also Fig. 7) to be presently described. The link 90 is provided with a slot 108 the upper end of which engages'the stud 92, and is held in engagement therewith by means of a spring 109 stretched between the stud 92 and a stud 110 on the link 90.

Movement of the total control lever 30 out of its add position will cause the shaft 103 to be rocked in a clockwise direction (Fig. 2') by means of arms 97, 99 and 102 rocking the arm 104 in a clockwise direction and by means of a link 105 rocking the arm 93. This movement of the arm 93 assisted by the spring 109, moves the link 90 toward the left (Fig. 1).

Near the end of the first cycle of operation the link 90 is given an additional movement toward the left (Fig. 1) by a cam 115 (Fig. 7) mounted to rotate on the stud 37 in a recess in the gear 36. The cam 115 is held against rotation during adding operations of the machine by means of a sl-idable coupler 116 in a usual and well known manner. hen the arm 93 is rocked as above described, the pitman 106 will be moved toward the left (Fig. 7) to slide the coupler 116 to couple the cam 115 with the gear 36 to cause rotation of the cam 115. The pitman 106 is provided with two studs 118 between which an upwardly extending flange 119 of the coupler 116 projects. As the pitman 106 is moved toward the left (Fig. 7) the studs 118 will slide the coupler 116 therewith into engagement. with a notch 120 in the gear 36 thus coupling the cam 115- to the gear 36.

The pitman 106 is provided with an antifriction roller 125 (Fig. 7 which projects into a notch in the cam 115' when the total control lever is in the add position, but which is moved into a cam race 126 of the cam 115 when the total control lever is moved out of its add position as just described.

The cam race 126 is so timed that near the end of the first rotation of the shaft 33, the pitman 106 will be rocked still farther toward the left (Fig. 7) thereby giving the arm 93 an additional clockwise movement.

Just before the cam race 126 moves the pitman 106 toward the left, the cam 50 will move the arm 48 to its lower position as shown in Fig. 5. After the arm 48 has thus been lowered the cam race 126 will cause the arm 93 to be rocked in a clockwise direction as just described which movement will be enough to permit the link 90 to be moved to the left (Fig. 5) to cause the hook 52 to be moved into tie path of the stud 51. At the end of the first rotation of the shaft 33 the strong spring 43 raises the arm 48. As the arm 48 is raised the stud 51 will cam the hook 52' and link 90 toward the right (Fig. 5) against the tension of the spring 109. After the stud 51 has passed the hook 52, the spring 109 moves the link 90 and hook 52, toward the left (Fig. 5) thereby moving the hook beneath the stud 51. Near the end ofthe second rotation of the shaft 33' the arm 48 is again lowered, as shown in Fig. 6, thereby lowering the hook 52 to rotate the gear 56 in a clockwise direction, as before described. At the very end of the second cycle of operation of the shaft 33 the spring 43 will again raise the arm 48- thereby disengaging thev stud 51 from the hook 52.

The total control lever 30 cannot be returned to its add postion until the machine has reached its home position. For this reason the hook 52 cannot follow the arm 4-8 to its normal position when said arm is raised by the spring 43 near the end of the second cycle of operation of the machine. However, the hook can follow for a short distance, until the roller 46 engages the lug 45, whereupon it will be prevented from moving, because at this time the total lever cannot be moved. When the cam 115 (Fig. 7), reaches its home position and the roller 125 is in position to again engage the notch, as shown in Fig. 7, the pitman 106 will be free to be moved toward the right thereby permitting the counter-clockwise rotation of the arm 93. This will permit the spring 75 to complete the counter-clockwise rotation of the collar 47 thereby causing the lever 30 to be returned to itsadd position. However, this movement will not. take place. until the shaft 103 is free. to be moved by the cam slot 96 in the total lever. Thus when the roller 125 moves into the notch in the earn 115, the shaft 103 will be free to move and therefore the cam slot 96 can rock the shaft 103 thereby permitting the total control lever to be returned to its add position.

Movement of the arm 93 when the total lever is returned to its add position will cause the link 90 to be moved toward the ri ht (Fig. 6). For this reason the link 90 is cut away to the edge 135 (Fig. 6) so that even though the link 90 shall. have been moved toward the right from the posi tion shown in Fig. 6, the stud 95 will be cammed into the notch 89 by means of the spring 7 5.

lVhen the control lever 30 is moved into any one of the total-taking positions except the first position below adding position, the lug will not be in the path of one of the rollers 46, and therefore the control lever will not be returned to its add position at the end of the operation. Thus it is seen that the only position from which the total control lever may be automatically returned, is the first position below add position, which first position is the one for controlling the totalizer for printing the total of an itemized transaction or sale.

0 aeration A brief description of the operation of the mechanism will now be given. During adding operations the total control lever is left in its add position in which position the lug .5 is out of the path of the rollers 4.6 for returning the lever and therefore the lever will not be affected during adding operations. The means for rotating the collar 47 is normally held in a position in which it will not become effective to rotate the collar, and therefore during adding operations the mechanism does not function.

When the total lever is moved to the first position below add the hook 52 is moved a short distance, but not far enough to become engaged with the stud 51. After the arm has been lowered the hook 52 is moved toward the left far enough to be moves into the path of the stud 51. Upon upward movement of the arm 48 the hook 52 snaps over the stud 51 and upon subsequent downward movement of the arm 48 the hook 52 is lowered to rotate the gear 56 in a' clockwise direction and stretch the total lever restoring spring 'Z5. The gear 56 is rotated independently of the collar 47 during this movement, due to the latch 59 and the clutch connector, but when the gear 56 receives one-half rotation, the

latch 59 is disengaged from the collar 4L7.

Near the end of the second cycle of operation the arm 18 is raised and as the machine reaches its home position the hook 52 is released thereby permitting one of tie rollers 46 to return the total lever to its add position.

If the lever ismoved to any other position except the first position out of add the mechanism for returning the total lever will be operated idly because the lug 45 will not be in the path of the rollers 46. Thus the total lever will only be returned from its first position out of add.
